- Lanthanum(III) triflate catalyzed direct amidation of esters
-
Lanthanum trifluoromethanesulfonate is an effective single-component catalyst for synthesizing a variety of amides directly from esters and amines under mild conditions. Highly selective amidation of esters and amines, as well as catalyst-controlled amidation of esters, demonstrated the effectiveness of the catalyst system.

- Anti-Helicobacter pylori agents. 4. 2-(Substituted guanidino)-4-phenylthiazoles and some structurally rigid derivatives
-
In order to find a new class of anti-Helicobacter pylori (H. pylori) agents, a series of 4-[(3-acetamido)phenyl]-2-(substituted guanidino)thiazoles and some structurally rigid analoges were synthesized and evaluated for antimicrobial activity against H. pylori. Among the compounds obtained, high anti-H. pyrori activities were observed in benzyl derivative 34 (MIC = 0.025 μg/mL) and phenethyl derivatives 35 and 36 (MIC = 0.037 μg/mL and 0.017 μg/mL). Though alkyl derivatives generally showed lower activity, the 2-methoxyethyl derivative 28 preserved significant activity (MIC = 0.32 μg/mL) and also exhibited more potent gastric antisecretory activity than ranitidine. Structural restriction by bridging between the thiazole and the phenyl rings with an alkyl chain did not improve the activity in this series.

- 1,3-Dihydro-1,3-diacetyl-2H-benzimidazol-2-one: A new versatile and selective acetylating agent
-
1,3-Dihydro-1,3-diacetyl-2H-benzimidazol-2-one (4, DABI) was proven to be a versatile and selective acetylating agent for amines. Selectivity and reactivity are not only superior than those of other known acetylating agents, but also products could be easily separated with excellent yield.

- Nucleophilic Attack vs General Base Assisted Hydrolysis in the Reactions of Acetic Anhydride with Primary and Secondary Amines. pH-Yield Studies in the Recognition and Assessement of the Nucleophilic and General Base Reactions
-
The reaction of a set of primary and secondary amines with acetic anhydride in water at 25 deg C gave variable yields of the N-substituted acetamide in seven of the eight amines studied.The yield of the amide as a function of pH revealed the incursion in the most cases of a general base assisted hydrolysis of the acetic anhydride by the amine.From the pKa's of the amines and kw and kOH for acetic anhydride (the specific rates for the reaction of the anhydride with water and hydroxide, respectively), both kDN (for the formation of acetamides) and kGB (for the general base assisted hydrolysis) may be readily evaluated by fitting the pH-yield-data to pH-yield or pH-product ratio profiles.The reactions of ethyl chloroformate with aniline and benzylamine in water also showed the presence of the general base assisted reaction.It is concluded that (a) pH-yield data provide a new way of showing the existence of general base assisted hydrolysis in the presence of a direct nucleophilic displacement reaction, (b) the general base promoted reaction is sufficiently prevalent that it would be prudent to check specifically for its presence in any investigation of mechanisms of acyl transfer in water, and (c) until the extent of general base promoted hydrolysis can be predicted adequately, the possibility of such a reaction makes it difficult to predict yields of the products of the direct attack, and hence just how suitable a medium water may be for a particular preparative acyl transfer reaction.

- pH optimization of nucleophilic reactions in water
-
We present a way of prescribing the pH for a reaction so as to obtain either (a) maximum yield in competition with hydrolysis or (b) selective reaction at either of two sites in such nucleophile-electrophile reactions as C-alkylation of acidic ketones and the acylation and sulfonylation of amines. First, we derive the following general equation for pHmax, the pH giving the highest yield of the product (P) of the reaction of a nucleophile (Nu) with a hydrolyzable electrophile (E) in water: pHmax = 1/2[log (kw/kOH) + PKw + pKw] (kw and kOH refer to the water- and hydroxide-promoted hydrolyses of E, Kw is the autoprotolysis constant of water, and Ka is the acid dissociation constant of NuH+, the conjugate acid of Nu). pHmax thus depends on a property of E (namely, kw/kOH) and a property of Nu (the pKa of NuH+), but not on the rate constant for the reaction of E with Nu or the concentration of Nu. We then deduce analogous approximate equations for maximum selectivity for reaction at either of two nucleophilic sites, specifically, equations giving pHxmax and pHymax, the pH values for the maximum yields of the respective products (Px and Py) of the reactions of E with the two nucleophiles. We find that (a) pH-yield profiles calculated from the equations concur with observed yields for reactions under pseudo-first-order conditions and (b) preparative experiments at the estimated pH values give good to excellent yields of clean products and high selectivity in both the C-alkylation and Schotten-Baumann reactions.

- AROMATIC HYDROXYLATION OF BENZYLAMIDES BY POTASSIUM SUPEROXIDE
-
N-benzylamides react with potassium superoxide in benzene in presence of 18-crown-6 ether to give ortho and para hydroxylated products.A mechanism is proposed for this reaction, involving the nucleophilic attack of superoxide anion to amide carbonyl and hydrogen abstraction from benzyle methylene by the substrate-superoxide adduct.
